Reactive armour. Reactive armour is a type of vehicle armour used in protecting vehicles, especially modern tanks, against shaped charges and hardened kinetic energy penetrators. The most common type is explosive reactive armour (ERA), but variants include self-limiting explosive reactive armour (SLERA), non-energetic reactive armour (NERA ...
Light-dependent reactions are certain photochemical reactions involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions: the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI). PSII absorbs a photon to produce a so-called high energy electron which ...
Seaborg Technologies is a private Danish startup.It is developing small molten salt reactors. [2] [3] Founded in 2015 and based in Copenhagen, Denmark, Seaborg emerged as a small team of physicists, chemists, and engineers with educational roots at the Niels Bohr Institute, CERN, ESS (European Spallation Source) and DTU (Technical University of Denmark) who share a common vision of safe ...
Kontakt-5 is a type of second-generation [1] explosive reactive armour (ERA) originating in the Soviet Union. Due to the shortcomings of Kontakt-1, NII Stali further developed the reactive armor to Kontakt-5, so that it also repels APFSDS projectiles, which is not as effective in combat as stated. In addition, Kontakt-5 is not just additional ...
The Bezold–Jarisch reflex (also called the Bezold reflex, the Jarisch-Bezold reflex or Von Bezold–Jarisch reflex [1]) involves a variety of cardiovascular and neurological processes which cause hypopnea (excessively shallow breathing or an abnormally low respiratory rate), hypotension (abnormally low blood pressure) and bradycardia (abnormally low resting heart rate) in response to noxious ...
Ø (or minuscule: ø) is a letter used in the Danish, Norwegian, Faroese, and Southern Sámi languages. It is mostly used as to represent the mid front rounded vowels, such as [ø] ⓘ and [œ] ⓘ, except for Southern Sámi where it is used as an [oe] diphthong. The name of this letter is the same as the sound it represents (see usage).
Reactive lymphocyte. Reactive lymphocyte surrounded by red blood cells. In immunology, reactive lymphocytes, variant lymphocytes, atypical lymphocytes, Downey cells or Türk cells are cytotoxic (CD8 +) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 μm in diameter with varying size and shape.
Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. [4] Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the ...
